Desalination Evaporators
Tube installation, rolling and tube end welding for titanium and copper tubes in desalination evaporators.
What makes these jobs different
- Thin-wall titanium or copper tubes in large numbers
- Rolled and welded joint quality decides how long the evaporator lasts
Recommended tools
- SR servo tube rolling system: constant torque, traceable records
- WZM1-200TX-B orbital TIG welder: autogenous welding of titanium tubes without filler wire
- For retubes: YKB tube pullers and DNQ internal tube cutters
References include on-site fabrication of desalination evaporators in China and titanium / copper tube replacement on evaporators at a coastal power plant.
